Aight den, since you pitched such a fit....LOL.....I pulled a quart of gear oil out and replaced it with a quart of the Lucas. Got purdy hot here today so we probably ain't gonna drive her today. We'll drive her this week for sure. Man that stuff is THICK. I bet it's every bit of 140 weight. LOL It has one quart of Lucas and a half quart of 90 weight. That's all the little rear end holds is 1 1/2 quarts. LOL
